The paper shows how to design and implement intelligent, service oriented systems for management of free places in distributed car parks. The idea of SOA technology is widely used. It is assumed that a state of every car park is automatically determined by a special electronic infrastructure including IoT solutions. The information received from such an infrastructure is sent to the main management system, which processes it and, on the basis of current knowledge, offers a set of smart services for drivers. In consequence, they can find a free place in the car park which is situated at the shortest distance from their destination. Dependability of smart services depends on basic information coming from such car park infrastructures. The most important decision is the one as to whether a place in a car park is free or occupied. Therefore, in the paper some experiments were carried out to evaluate the correctness of determining the occupancy of a particular car park lot. Moreover, the flexibility of the presented solution is also emphasized.
